A bunch of inconsequential tremors or wait for the "big one"?

Cuadrilla commissioned the study under review, which found a high probability that hydraulic fracturing of its Preese Hall-1 well triggered seismic events last April and May. The well was completed in a Bowland basin shale, which Cuadrilla has said might hold 200 tcf of natural gas in place in its 437-sq-mile license area between Blackpool and Preston.Okay.
The Cuadrilla study said none of the seismic events caused structural damage. The largest event, in April 2011, had a magnitude of 2.3.
The study said the events resulted from a rare combination of geological conditions around the well.
